From my experience, you need level 13 or 14 to get the Repair I enchant on thaumium. I think the Axe of the STream & other higher tier Thaumium tools are slightly more enchantable, though I'm not entirely sure.
Permission to distribute the Magic Bees addon for Forestry is granted to any modpack. Permission to include Forestry is not required, but very helpful to run. (Thaumcraft 3 is no longer required.)
